Two students are canoeing on a river. while heading upstream, they accidentally drop an empty bottle overboard. they then continue paddling for 60 minutes, reaching a point 2.0 km farther upstream. at this point they realize that the bottle is missing and, driven by ecological awareness, they turn around and head downstream. they catch up with and retrieve the bottle (which has been moving along with the current) 5.0 km downstream from the turn-around point. (a) assuming a constant paddling effort throughout, how fast is the river flowing? (b) what would the canoe speed in a still lake be for the same paddling effort?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
